LOL.
Not even sure if you are being serious right now....
TSMC owns like 12% of their stock shares, they would have to give intel ALL of their stock to buy them out which would mean that intel would then own TSMC, well, at least as much as TSMC owns TSMC right now.
Going by your only stocks theory anyway.
But as I say in the post you quoted, they would have to pay all the assets and that is the very least if intel really had enormous money problems and would let it go at cost, that's still roughly twice as much as what TSMC has as stocks.
I also have no idea if either company has given out 100% of their company as shares or if there is a part that still belongs to...whoever.
